About Ball and Roller Bearings
More
Permanently Lubricated Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.
Sealed bearings have even better resistance to dust and contaminants than open bearings.

Cylindrical Roller Bearings
With cylindrical rollers to distribute load over a large surface area, these bearings are often used to support heavy loads at high speeds in applications such as power generation and metal recycling. A cage prevents the rollers from touching each other, reducing friction for high-speed use. All of these bearings have an inner ring that's flanged on one side, so they only allow heat expansion in one direction. The bearings can be taken apart, so you can install them with precision and quickly dismantle them for maintenance or replacement.
